oil cooler lines leaking at radiator
 

I have a new radiator with the quick connect lines. Once i installed the new radiator i noticed the oil cooler lines were leaking at the radiator fittings. I figured since the top line had a nice scrath on the flare and both lines had rust i would replace them with factory lines and kill two birds with one stone. After replaceing the lines they leaked even more at theradiator. I'm going to try the old radiator fittings and see if that fixes the issue. Any ideas? 3.4l 2004 monte carlo

i had something similar happen when i upgraded my radiator... picked up the wrong year radiator and had to go back for the correct fittings.

cheap fix, even cheaper at a pick-a-part. good luck.
